Patent abstract
A propeller straightening apparatus utilizes a pair of adjustable hydraulic cylinders to apply pressure to a selected propeller blade of the propeller. Adjustments can include lateral, longitudinal and tilt angle. A propeller mount holds the propeller in a fixed position during straightening. The mount can be quickly loosened so that the propeller can be rotated to present a different propeller blade to the hydraulic cylinders. The cylinders have polyurethane tips portions that help grip the surface of the propeller. The apparatus can bend a selected propeller blade to change rake and/or pitch.
